A total of 12 people died on city roads during 2014, in a year that saw a 37 per cent increase in Thames Valley traffic deaths.
In 2013, there were 57 deaths in the region in comparison to 78 last year following a rise in the numbers of pedestrians, cyclists, car drivers, car passengers and heavy goods vehicles drivers killed on the road.
Chief Inspector Henry Parsons, head of roads policing, said: “The rise in fatal collisions across the Thames Valley is exceptionally disappointing with each fatality causing untold misery and distress to the loved ones of the people who died.
“Each statistic represents a family which has lost someone in sudden and tragic circumstances and our thoughts remain with families affected in this way.
“Specially-trained family liaison officers are appointed to provide support in these circumstances.
“The causes of the collisions are varied, with many still under investigation.
“Some of these involve criminal investigations for causing death by dangerous driving or death by careless driving.”
Milton Keynes had the lowest number of fatalities in the Thames Valley.
In Buckinghamshire 20 people died in 16 collisions, 19 people died in Berkshire in 18 collisions, 12 people died in Milton Keynes in 11 collisions and 27 people died in 27 collisions in Oxfordshire.
The levels of motorcyclists and light goods vehicles drivers and passengers killed on the Force’s road network have reduced.
Chief Inspecotr Parsons added: “Our team works in partnership with local authorities and other emergency services to improve road safety. We will continue to deliver targeted enforcement to reduce the risks of collisions.
“In addition we will continue to deliver innovative, appropriate, alternatives to prosecution as well as our ‘Safe Drive, Stay Alive’ package aimed at young people and our ‘Bike Safe’ campaign for motorcyclists.”
